TO ALL WHOM IT MAY CONCERN: i

Be it known that I, ALBERT VOSE, ofthc town of Pittsiield,in the county of Rutland, in the State of'Vermont, Vhave invented a new and useful Machine for Loading I-Iay; and I do hereby dcclare that thefollowing is a full, clear, and exact description of the construction and operation yof the same, reference being had `to the i annexed drawings, making a part of-this specification.

` The nature of my invention consists in the construction of a machine for loading hay from the windrow, constructed to originate its power fromYfriction-bloeks attached t'o the two arms of the fork, connected with the two rear wheels of any common hayfwagon to which it may be attached, and be operated nby a combination `of, levers and ropes connecting the fork with'the rear wheels, and gathering the hay withthe semicircrflar rake, in such a manner as to load the hay very fast; the machine to be managed and controlled by the driver on the load.

To enable others skilled in the art to make and use my invention, I will proceed to describe its constructionand operation. i

Figure 1 is a plan or top view of a hayswagon, having my improved hay-'loader attached, the wagon-body or rack being Apartly broken away, for the purposeof more clearly showing thc arrangement of the parts of the loading-attachment.

l Figure 2 is a'side elevation of the same; and `Figure Sis also aside elevation, showing the fork-carrier arms thrown up into a vertical position, for loading. the hay upon the wagon, as hereinafter'explained. i

I construct my machine as follows :L I attach to any common hay-wagon a square Yframe of'wood, represented by'a a a a,'f1g. I, to the under side of the body, fastened to it by four iron bolts, the ends of the frame a a passing the outside of the rear wheels opposite the ends of the axle. To this I attach the whole machine, so that it may be taken off when desired. To this frame, on the inside, opposite the centre of motion of'pthe wheels, I attach the arms b b, on each side ofthe wagon, by a small axle, j, made fast intheframc a a, so that the centre of the motion of the'arms b L corresponds with that of the wheels-: c. I connect the outer'ends of the arms 5 b by the har of wood c. To cach of these arms b I attach the friction-blocks d d with alloose belt,` so that they may be drawn against'the wheels by the lever eLbeing connected with it by the rod z', the lever e being operated by the rope nz, which is attached to its longest arm, and passes down through therings e e, and connects together, and passes on the under s ide ofthe bedyand up to the drivers stake, where he can operate` it at pleasure. j I also attach the ropes 5 to the arm n: x, for the purpose of throwing back the fork afterit is f raised, l The rope 5 is attachedto rope m in such a way tha t, when the fork is up, the end of rope m, attached 'lo lever e, is slack, and rope 5 is tight; hence a slight pull hy the driver throws the fork back upon thchay, and rope 5 is made loose, and rope m is tight; then a pull hy the driver at rope m throws on the friction-blocks v d d, and shuts the forks upon the-hay, by means' of the rods u, lcvcrs t', and chains w, which connect them with lever e und rope m. The hay is thus grasped by the ferns, and the friction-blocks d' being simultaneously applied to the wheels, the arins Z1, upon which said blocks are mounted, turning upon the same centre with the wl1eels,l"nre fastened thereto, and, by the rotation of the wheels, as the machine is drawn forward, are raised into a vertical or nearly vertical position, (see iig. 3,) carrying the loaded fork with them, until the lever c strikes the projecting arm or stop g, and is thrown hack, loosening thc friction-blocks cl d, andrelcasing the forks q q, which are thrown open by the spring t, dropping the hayupon the load, leaving the fork ready to be thrown back, hy rope 5, upon the hay, which is gathered by rakcj.

I will next dc-scrihc the forks rl q, which are attached to the frecl ,'rcvol.'ing cross-piece o, hy means of the loose bolts s s, so as to open and shut upon the hay. The forksq q are thrown open by thc coil-spring t, by which they are connected at the top, and arc connected to the right-angled levers v v by the chains w w. The levers v o are connected with the levers c @by the reds un, so that when the friction-blocks cZvcZ arc thrown upo'n the wheels by ropes m m, the forks g q shut up to the position shown bythe dotted lines, and made fast in the hay, there remaining'until levers c e are thrown back by the blocks gg. The rods u u and are so attached to levers c e as to form an eccentric, so that, when rope m pulls them in position to workthc fork, the friction- Y block is made fast to the wheel, land the fork will bekeptishut Lntil levers e e are thrown back by blocks gg, as

will be seen at figs. 2 and 3.

The rakefis made in a sernicircular form, ifirith spiral teeth,) so as to gather the hay to the centre, ready for the fork, and is attached to'the frame a aiby the arms u n, by zi loose joint that m'ayfbe easily detached operating just in rearof the fork, thus combiningV the forks gg with thsemicircuinr rakef, .to operate substantially as described.

i v Claims. What I claim as my invention, and desire to secure -by Letters Patent, is-

1. The forli-arm b, hinged or.pivoted to the frame in line with the axle, and operated by means of-t'riction blocks, as'described'. I

2. The friction-blocks d, in combination with fork-:mn b and eccentric-levers e, arranged as describedv 3. The forlbarms Z1., in combination with the freely-swivelling forkb:1r o, operated as described. i 4. The'forlis g, pivotedl in swivelling-bar o, and operated by meansvol levers o, and rods, cords, or chains, substantially as described.

y 5. The levers v, -mounted'on fork-bars or arms in combination with the fork g, substantiallyr as described. 6. The combinationl of forks g, spring t, chains w, and levers v, with the fork-urm b, substnn tielly as and for the purpose set forth. i

7. T llevmeans for opening llnnd closing the lifting-forks, lin conibinn-tionlwith a. means for operatingtbe friction-blocks, or tbeiriequivalcnt, wbcreby'tbey are operated simultaneously? es described.

S. YThe lever e, for closing the forks and applying-tbe friction-blocks, as described, in combination with the arms g, for releasing tbe stime,v as described. Y

9. '-'lhe extension :o ofthe lpivoted fork-bars ,'in combinutionwith cords or chains 5, operating als described. 10. The curved or ser'nic'ircular reke-head, or its equivalent, arranged in rear of and operated in connection with the lifting-fork, substantially as described.

ALBERT VOSE.
